Abstract

A process for producing a glyceryl ether which comprises supplying a compound represented by the general formula (I): (I) (wherein R represents a C1-20 hydrogen group in which part or all of the hydrogen atoms may have been replaced with a fluorine atom; OA's may be the same or different and each represents C2-4 oxyalkylene; and p is a number of 0-20) and water to a reactor and hydrolyzing the compound under such conditions that the water is in a subcritical or supercritical state. The process for glyceryl ether production includes: a step (1) in which the water is recovered from the reaction mixture resulting from the hydrolysis, regulated so as to have a pH of 3.5 or higher, and then supplied to the reactor; or a step (2) in which the water recovered from the reaction mixture resulting from the hydrolysis is filtered through a reverse osmosis membrane and the treated water obtained is supplied as recycle water to the reactor.
